Key Features
Overview
The Festool FSZ 300 Screw Clamps are a pair of specialty screw clamps built for the Festool guide rail and Multifunction Table system. This is a screw clamp designed for securing workpieces during precision cutting. routing. and sanding. Model Number 489571. If you use Festool FS guide rails or an MFT work surface. these clamps give you a clean. reliable way to hold stock without getting in the way of the cut.
What matters here is not just the 300 mm. or 11-13/16 inch. clamping width. It is how that reach works inside the Festool system. The specialized clamp head is designed to fit the holes and channels in the Festool MFT and slide into the bottom T-slot of Festool FS guide rails. That lets you secure material from below or from the edge. which helps keep the top of the work area clear for saws. routers. and sanders.
The traditional screw clamp layout is familiar. but the shape and fit are what make these different from a standard shop clamp. Instead of fighting awkward clamp placement or having a bar clamp block your saw track. the Festool FSZ 300 Screw Clamps are built around the way Festool users actually work. That means faster positioning. more repeatable setups. and less time spent moving clamps just to finish a cut.
Festool specifies a solid steel version. and that is the right call for this kind of accessory. A clamp like this needs to stay straight. apply even pressure. and hold up to repeated tightening on the bench and on the job. Whether you are locking down sheet goods on an MFT. securing trim for routing. or holding a workpiece steady for sanding. steel construction gives these clamps the durability and clamping confidence serious users expect.
These clamps are especially useful in precision workflows where movement ruins the result. When you are cutting to a line with a guide rail. routing an edge. or sanding a part that wants to walk across the table. stable hold-down pressure saves rework. Because the clamps work with Festool system holes. channels. and rail slots. they support the kind of controlled setup that cabinet installers. finish carpenters. furniture builders. and detail-focused DIY users care about.
Compatibility is a big part of the value. Festool lists these screw clamps as suitable for FS/2. FS/2-KP. FSK. and MFT. In plain terms. they are meant for users already invested in the Festool guide system and worktable platform. If that is your setup. this is one of those accessories that makes the whole system work better. If you are not using Festool rails or MFT tables. the specialized head design is more specific than a general-purpose clamp. so the real advantage is for the Festool user.
Who should buy them? Anyone using a Festool track saw setup. guide rail system. or MFT table for woodworking. finish work. or repeatable bench tasks. They are a smart pickup for woodworkers and installers who want secure clamping that does not interfere with the tool path. And since this pack includes two clamps. you can stabilize a workpiece at both ends right out of the box.
